Thats good info John, thanks. The intent is to find a good driver engine I can slap in the bird now, then slowly and correctly rebuild the original engine. I've always treated the car as a cruiser. I make noise once in a while but no real racing.
My rebuild options are limited locally (only one good shop in the area and they are backlogged out the ying-yang), and according to Tom in KY and a few others BUTLER Pontiac builders takes a LONG time.
But we'll drive on with this and take is one step at a time.
'68 428 HO M3 Monster, 4-on-the-floor! Need I say more?
